  • Research Highlight |

    A study shows that congenital heart defects in Down syndrome are in part caused by increased dosage of the DYRK1A gene, which lies on chromosome 21, leading to reduced proliferation and mitochondrial dysfunction in cardiomyocytes.

  • Review Article |

    In this Review, Varga and colleagues provide an overview of the evidence on immune checkpoint inhibitor-induced heart failure and cardiac dysfunction that is unrelated to myocarditis, and discuss how pharmacological targeting of immune checkpoints might be a potential strategy to treat heart failure.

  • Clinical Outlook |

    Heart valve replacement in newborn babies remains an unsolved problem because currently used heart valve implants do not grow. This lack of implant growth mandates serial re-operations until adult-size valve implants can be fitted. Partial heart transplantation is a new approach to solve this problem by transplanting only the part of the heart that contains the necessary valve.

  • Research Highlight |

    Anti-inflammatory therapy involving IL-1β inhibition might reduce the risk of cardiovascular events in individuals with clonal haematopoiesis by increasing the number of fibroblast-like cells in the fibrous cap region of atherosclerotic plaques, thereby stabilizing the plaque and reducing the likelihood of rupture.

    • Gregory B. Lim

  • Review Article |

    In this Review, Guzik and colleagues discuss immune and inflammatory mechanisms of hypertension, including upstream regulators and downstream effectors as well as the complex interplay between the immune system, blood pressure regulation and end-organ damage, which can help to identify new targets for therapeutic interventions.

  • Review Article |

    Macrophages in atherosclerotic plaques can undergo apoptosis and several forms of regulated necrosis, including necroptosis, pyroptosis and ferroptosis. In this Review, De Meyer and colleagues describe the various forms of programmed macrophage death in atherosclerosis and the potential therapeutic implications.

  • Comment |

    Representation of Black patients in cardiovascular clinical trials remains dismally low, reflective of systemic and structural barriers, which can lead to missed opportunities to meet community-identified needs, understand responses to medical therapies and improve cardiovascular care. Innovative, multilevel strategies focused on Black communities are warranted to increase enrolment of this population into clinical research.

  • Comment |

    Mosaic loss of chromosome Y (mLOY) refers to the condition in male individuals in which a detectable fraction of cells lose the Y chromosome. Prevalent in haematopoietic cells, this common somatic mutation is associated with decreased longevity and an increased risk of age-related diseases, including cardiovascular disease. Haematopoietic mLOY provides further insight into the sex-specific disparities that exist in disease susceptibility.

    Gene therapy involving adenine base editing can correct a pathogenic variant in the Scn5a gene and alleviate arrhythmia phenotypes in a mouse model of long QT syndrome type 3.

  • Comment |

    Racial and ethnic disparities in cardiovascular health in the USA result in a persistent mortality gap between white and Black individuals, increase health-care costs and compromise an egalitarian society. Solutions to racial inequities require risk factor control and the implementation of evidence-based medicine and anti-racism policies. Overcoming these disparities is not only a practical necessity, but also a moral imperative.

    Aster proteins are involved in the non-vesicular transport of cholesterol derived from dietary lipids in the small intestine from the plasma membrane to the endoplasmic reticulum in enterocytes.

    In the ORBITA-2 trial, percutaneous coronary intervention was associated with a lower angina symptom score compared with a placebo procedure in patients with stable angina who were receiving minimal or no antianginal medication.

    Treatment with the glucagon-like peptide 1 receptor agonist semaglutide, administered subcutaneously at a dose of 2.4 mg once per week, reduces the risk of major cardiovascular events by 20% compared with placebo in patients who are overweight or obese and with pre-existing cardiovascular disease but without diabetes mellitus, according to findings from the SELECT trial.

  • Research Highlight |

    Data from the ARIES-HM3 trial show that excluding aspirin from the antithrombotic regimen in patients with advanced heart failure and a left ventricular assist device reduces the number of bleeding events and does not increase the risk of thromboembolism.

  • Research Highlight |

    Activation of a specific set of vagal sensory neurons connecting the ventricular wall of the heart to the area postrema in the brainstem causes mice to faint. This finding defines a cardiac reflex that recapitulates characteristics of human syncope.

  • Research Highlight |

    Two new studies using cryo-electron microscopy describe the structure and conformation of myosin in the cardiac thick filaments and how it interacts with other thick-filament proteins, such as titin and cardiac myosin-binding protein C, in mammalian hearts.

  • Research Highlight |

    Treatment with the small interfering RNA patisiran preserves functional capacity and improves health status and quality of life in patients with transthyretin cardiac amyloidosis, according to data from the 12-month double-blind period of the ongoing APOLLO-B trial.

  • Clinical Outlook |

    Transcatheter aortic valve implantation (TAVI) has become an important treatment option for aortic stenosis, even among younger patients, with similar rates of efficacy as compared with surgical valve replacement. However, complications including device failure persist; these can be addressed by surgical explantation and repeat TAVI. Ongoing research emphasizes the long-term potential of TAVI as an alternative to surgical intervention for aortic stenosis.

  • Review Article |

    The NLRP3 inflammasome can sense cardiac ischaemic and non-ischaemic injury, amplify the inflammatory response and induce inflammatory cell death. In this Review, Toldo and Abbate describe the role of the NLRP3 inflammasome in numerous cardiac pathologies and summarize evidence on the use of agents targeting the NLRP3 inflammasome and related cytokines.

  • Evidence-based Guidelines |

    A panel of experts from the World Heart Federation provide a revised set of guidelines for the echocardiographic detection of rheumatic heart disease (RHD) in patients living in RHD-endemic regions. The guidelines provide updated screening and confirmatory criteria, as well as a new stage-based classification of RHD based on risk of disease progression, which will improve the diagnosis and subsequent management of patients with RHD.

  • Comment |

    For patients with heart failure and reduced left ventricular ejection fraction, intravenous iron is likely to deliver clinical and prognostic benefits for those with anaemia and transferrin saturation <20%, especially if serum ferritin exceeds 100 μg/l. A serum ferritin of <100 μg/l does not appear to be useful as a marker of iron deficiency.
